PH - Soil.... Going in at 6.4 coming out at 5.7

My plants look healthy... Should I up the PH of the water/nutes going in? Or should I just let it be?

just let it be
why mess with something thats already fine

I usually shoot for about 6.3 for watering because my water tends to drift upwards as it evaps. You are fine as long as your plants are looking healthy. Trying to bring it up a very high amount could just cause stress and ph flucuation burn. GL

thats very unusual for your ph to out lower man , are u testing your ph b4 or after u add nutes to your water?

Another possibility is your nutes. Some brands recommend that you let the solution sit about an hour before ph adjustment because the buffers within the nutes themselves need time to work.

I test before I put them in... When I put them in its are 6.3 (perfect for soil as far as I know). Once in awhile I water till run off and then test the run off. I tested the run off and its at 5.7.... I have a digital PH meter and its bang on, not some cheapy... What do you think? I really wanna get this issue solved. To be honest I don't think leaving it is an option..Yes the plants look healthy but at 5.7 they can't be eating all the nutes...

Thanks for the help!!!!

All Advanced... I haven't seen anything about that... Anyone else know if I should be doing this with Advanced products?

soil buffers the PH, it is wrong to think that a 5.7 runoff is stopping your plant from getting nutes what happens is the soil usually PH'd around 7 will adjust the ph up as the plant wicks the water and uses nutes in the PH range slowly buffering the PH back up to nuetral as the water is wicked off as this happens nutes are taken up in the various PH ranges
